ASEPTIC CONTAINER FOR LONG-HANDLED BROAGHES.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed November 8, 1915. Serial No. 60,226.

ber of small instruments which must be' kept at hand and readilyaccessible for immediate use so that he can quickly exchange one toolfor another by reaching out with one hand while the other is occupiedwith the patient, and it is essential that these tools should besterilized after use, and should be kept in aseptic condition whileawaiting use. Among the tools thus frequently used are broaches of whichthe dentist requires a considerable number. Some of these are providedwith long handles of vulcanite or other suitable material by which thebroach may be held in the hand as for instance, the broach used forcleaning out the root canals or for putting dressings into the rootcanal of the tooth.

The object of the present invention is to provide a convenient form ofholder for long handled broaches and a container for the same, of suchconstruction that the broaches may be kept on the dentists work table inconvenient arrangement, spaced apart from each other and with the bladessuspended free from contact with anything, so that there will be nodanger of the broaches taking up germs while awaiting use; also to makethe holder and container of such form and material that they may bethoroughly sterilized by boiling or other means before receiving thebroaches. The container may or may not contain a sterilizing fluid, suchas alcohol, while the broaches are in position. a 4

The invention will be fully understood from the following descriptionwhen taken in connection with the accompanying drawings and the novelfeatures thereof will be pointed out and clearly defined in the claimsat the close of this specification.

In the drawings, Figure 1 is a vertical sectional view of a containerhaving therein a holder embodying the invention, the holder being shownwith broaches contained therein. Fig. 2 is a perspective view of theholder disk removed from the container and showing only one broach inthe holder. Fig. 3 is an enlarged sectional view of the disk, partlybroken away, showing two tubular pockets for broaches, one pocket beingempty and the other containing a broach. Fig. 4: is a view of one of thebroaches such as the device is intended to hold.

Referring now to the drawings, 1 is the holder disk, preferably ofcircular form, and made of glass or porcelain or other non-absorbentmaterial suitable to be boiled or dipped into a sterilizing fluidwithout injury to the disk. Said disk is made with a plurality ofperforations 2, and in extens'ion of each perforation there is adownwardly extending tubular pocket 3. This tubular pocket maybeintegral with the disk or may be of different material and inserted intothe perforation, either as desired. The broaches 4: are each provided.with a handle 5 of vulcanite or other suitable material permanentlyattached to the broach, and, as usually made, this handle has adownwardly tapering portion 6 at the lower end. The tubular pockets 3also may be tapered downward, the interior diameter of the pocket 3being less than the large diameter of the handle 5, so that when thebroach is inserted in the pocket, the handle will not slip down entirelythrough the pocket, but will be seated therein. Preferably the diameterof the pocket at the top should be about the same as the large diameterof the handle 5.

The length of the tubes forming the pockets 3 is preferably greater thanthe length of the tapering portions of the handles so that the tube willextend some distance below the lower end of the handle, thus furnishinga protection or inclosure for the blade of the broach 4 for at least aportion of its length. This prevents any possibility of the broachescoming into contact with each other as they might do by reason of thepossible slanting insertion of the handle in the pocket or wabblingmovement of the handle in the perforation if it were not for the pocketextending below the perforation.

A container 7 is provided which consists of a cylindrical jar ofsufficient diameter at the top to permit the disk 1 to be inserted andis provided with a ledge or internal an-, nular flange 8 near the top onwhich the disk 1 is seated at a sufficient elevation above the bottom ofthe box or container so that the lower ends of the broaches will be elevated above the bottom of the container.

A cover 9 is provided which shuts over the top 'of the container, saidcover being preferably of the same exterior diameter as the exteriordiameter of the container 7 and is formed with its lower end of reducedexterior diameter forming a shoulder 10 which rests on the shoulder 11forming the top of the container 7. When the broaches are not in use thecover will be left on, thereby completely closing the top of thecontainer so that no dust or foreignmatter can get into the container.When the breaches are in use, the cover will be vremoved. V The diskholder 1, vhowever, will be left in the container and the handles 5 willproject above the top of the container, all spaced apart from each otherso that whenever the dentist desires to use one 'of the broaches, it isvery easy to grasp one of them by the handle and lift it out of theholder.

VWhat I claim is:

1. A dental broach holder comprising a disk having a plurality ofperforations and tubular pockets formed in extension of saidperforations, in combination with a container consisting of a jar havingan inner annular shoulder near the upper end which annular shoulder nearthe upper end which forms a seat for the said disk holder, the

depth of the container below theseat forthe disk holder being suflicientso that when the broaches are seated in the holder the lower ends of thebroaehes will be out of contact with the bottom of the container, and aclose fitting cover for the container. 7

In testimony whereof I aflix my signature, in presence of two witnesses.
